What mass of CO2 (in kilograms) does the combustion of a 16-gallon tank of gasoline release into the atmosphere? Assume the gasoline is pure octane (C8H18) and that it has a density of 0.70 g/mL. Express your answer in kilograms to two significant figures.

Mass of CO₂ = 1.3 x 10⁵ kg

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

2C₈H₁₈ + 25O₂⇒ 16CO₂ + 18H₂O

16 gallon = 60566,6 ml

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
